for the woman pics, I wouldn't hit any of these, i'm not desperate.
now for the op, I think you kinda over did on your polite decline, faking ignorance naiveness, or just saying sorry i'm not interested works a lot better, but let's see why she did go after you several times, you was drunk, like you said drunk people lose a lot of control(I belive its a damn excuse) and she was hoping you be so drunk you would do anything, so be happy you could hold out, also she getting preggo after this would be likely, but even drunk as a skunk you turned her down so now she is pissed because even a drunk would refuse her.
I would turn the drinks down a little if you are drinking enough to don't remember most of night, I consider it bad, you are not in control of yourself.
other then that nothing diferent of a normal night out with friends
